2 bar tune question/Issue I'm trying to tune the base fuel map for my 2002 Camaro with APS twins and a 403. I've got my boost enrichment set to enable at 110 Kpa and to disable at 85 Kpa and it has a multiplier of 1.25 and should be commanding 11.70, which it does. The problem is when it goes past 110 Kpa, then drops back below 85Kpa, it continues to command 11.70 until I cut the car off. I'm stumped. Tune and Scan are both attached.

That does not make sense because the car ran fine with it set to 85 Kpa before I put the new engine in. Should come out of boost enrichment as soon as it's below 85 Kpa. With a small Turbo from the APS kit it can see in the boost to activate the Boost enrichment just under normal driving

Enable MAP Hysteresis: This value is subtracted from the enable MAP value. If the MAP reading drops below this value then PE mode will be disabled
110kpa -85kpa= 25 kpa is the value to hit AFTER boost enrichment for it to disable. If you set it at 5 kpa, 105kpa-5 kpa, 100kpa is required to exit boost enrichment. If this doesnt help then im not sure what the issue is. Maybe check the map sensor or the integrity of the OS.
